I have installed the THAR-ONE-SUB2 in my US WRX per the instruction guide, page page 7/11 T-Harness - Automatic & Manual Transmission

ASK:
1.) Why is the car not starting with the Yellow/Red and Yellow/Green separeted per the installation guide
2.) Does my US WRX have to follow the Canadian Vehicle steps, if yes why and if no what is the difference
Installation was simple as mainly 2 connectors and areplug N play. I master reset my Evo One, flashed the 2020 WRX firmware and follow the programming steps on page 8/11. When I get to step 5 to start the car, the car starts and shuts off immidiately, eventually not even turning the starter. The lights on the Evo One stay solid for Red and Blue and programming does not complete to follow up on the Dcryptor part. After a little troubleshooting I found that I can get the car to start if I reconnect the Yellow/Red and Yellow/Green wires I cut eariler making the car at least drivable again.
